BICYCLE-PROP.

SPECIFICATIONforming part of Letters Patent No. 717,271, dated December30, 1902.

` Application led May 7, 1902. Serial No. 106,331. (No model.)`

nesota, have invented new and useful Im` provements in Bicycle-Props, ofwhich the following is a specification.

My invention relatesto bicycle-props and the object of the same is toconstruct a simple device of this character for supporting a wheel andwhich can be folded up and carried by the rider.

The novel construction employed by me in carrying ont my invention isfully described in this specification and claimed, and illustrated inthe accompanying drawings, forming a part thereof, in which- Figure 1 isa side elevation of a bicycle supported by my prop. Fig. 2 is aperspective of my rack set up. Fig. 3 is an elevation of the samefolded. Fig. 4 is a detail section of the stem. Fig. 5 is a detail of amodified form of springs for expanding the legs.V

Like numerals of reference designate` like parts in the different viewsof the drawings. The numeral l designates a hollow stem plugged at 2 andtraversed by a longitudinally-extending slot 3, within which is mounteda rack-bar 4, bearing a series of teeth 5, beveled in one direction. Therack 4 is resilient, is rigidly secured at its lower end at 6, but isfree at its upper end. A pin 7, bearing a head 7a, is seated in theupper end of the rack 4 and extends through an aperture 8 in a sleeve 9,fitted over the upper end of the stem 1. The pin 7 serves as athumbpiece for operating the rack 4 to disengage it,

and the head 7L limits the inward movement` The sleeve 9 has anapertured lug thereof. 10 formed integral therewith, to which is pivoteda head 11, having an inclined rounded face 12 formed thereon and adaptedto engage the front diagonal bar 13 of the frame of a bicycle. A clip 14serves to hold it firmly in place, although this may be dispensed with.

A collar 15 is slidingly mounted on the stem 1 and is recessed at 16 toadapt it to be engaged by the teeth 5 of the rack-bar 4 to normallyprevent its upward movement. Ears 17 are formed on the collar 15, towhich legs Y5a on the upper end of the rack.

18 are pivoted. Brace-rods 19, pivoted at one end to the legsintermediate their ends and at their other ends to ears formed on acollar 20,- rigidly mounted on the lower end of the stem l, serve tosupport the legs. By this arrangement the spread of the legs can beregulated. A fork 21 is carried by the sliding collar 15 and is locatedto engage the tire 22 of the front wheel 23 of a bicycle. Curvedspringarms 24, mounted on the stem 1, serve to engage the sides of thelegs 18.

In operation my rack is set up, as shown in Fig. 1, with the face 12engaging the bar 13. The pin 7 is then forced back to release the collar15, when rthe springs 24 will force the legs 18 outwardly,expandingthem. The fork 21 is then set to engagethe tire of the front wheel, andthe teeth 5 on the rack will hold the collar 1.5 against allI upwardmovement. When it is desired to fold the rack, the pin 7 is once moreforced back to release the collar 15, which is then grasped in one handand pushed up until it is engaged by the ratchet The legs 1S will engagethe springs 24 and restore them to .their initial positions.

I do not wish to be limited as to'details of construction, as these maybe modified in many particulars without departing from the spirit of myinvention.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

1. In a bicycle-rack, the combination of a stem, a head mounted on theupper end of said stem and having an inclined face constructed to engagethe frame of a bicycle, a rack bar mounted on said stem, a collarmounted on said stem and engaged by said rack-bar, a fork carried bysaid collar and constructed to engage the front wheel of a bicycle, legspivoted to said collar, and braces positively connected to said legs andto said stem, whereby the height of said fork above the ground may beadjusted, substantially as described.

2. In a bicycle-rack, the combination of a stem, a head mounted on saidstem and constructed to engage the front bar of a bicycleframe,a collarslidingly mounted on said stem and bearing a fork constructed to engagethe IOO front Wheel of a bicycle, means for securing my hand n presenceof two subscribing Witsaid collar at any point, legs pivoted to saidnesses. collar, and braces positively connected to said legs and to saidstem, whereby Iche height; of TENS RASMUSSOM' 5 said fork above theground may be adjusted, Witnesses:

substantially as described. OHAS. S. ALLEN,

In testimony whereof I have hereunto set GEORGE J. ALLEN.
